Abstract: A drive assembly for conveyor belt comprises a pair of opposing end plates for mounting a conveyor drive and mounting assemblies for mounting at least one of a position limiter assembly, a scraper assembly, a combined limiter-scraper assembly and side guards. The scraper assembly and combined limiter-scraper assembly include a leaf spring that is selectively tensioned by a tensioning element on an end plate to bias the scraper blade of the scraper assembly into an operational position.

Abstract: A cleanable conveyor frame and a method for making a cleanable frame having a simplified frame design. Infeed and outfeed assemblies are movable between operating and cleaning positions. An outfeed assembly includes a drive for a conveyor belt and a scraper assembly. The scraper assembly comprises a scraper blade mounted to a mounting bar extending between two connecting plates and a leaf spring extending rearward from the mounting bar for biasing the scraper blade into contact with the conveyor belt.

Abstract: A cleanable conveyor frame and a method for making a cleanable frame having a simplified frame design. Infeed and outfeed assemblies are movable between operating and cleaning positions. An outfeed assembly includes a drive for a conveyor belt and a position limiter-scraper assembly. The position limiter-scraper assembly comprises a roller extending between two connecting plates mounted to outfeed mounting plates, a scraper assembly having a scraper blade mounted to a mounting bar extending between the two connecting plates and a leaf spring extending rearward from the mounting bar for biasing the scraper blade into contact with the conveyor belt.

Abstract: A flexible thermoplastic conveyor belt constructed of one or more belt segments having corrugated sidewalls. The one or more segments are joined end to end at one or more joints. The ends of the sidewalls at or near the joints are fastened together by fasteners to form a continuous sidewall along the length of the belt. The fasteners are toolless fasteners requiring no tools; they can be fastened and unfastened by hand alone.

Abstract: A cleanable frame and a method for making a cleanable frame having a simplified frame design. A hygienic conveyor frame assembly comprises a plurality of hollow tubular sections joined together to form an evacuated, sealed conveyor frame support structure that functions as a sterilization zone. An integral carryway is placed on the support structure. Lifters coupled to the conveyor frame can lift the carryway and conveyor belt for cleaning. Infeed and outfeed assemblies are also movable between operating and cleaning positions. A sensor can monitor the conditions of the frame interior to ensure that the vacuum is maintained and initiate a corrective action if the vacuum seal is breached.

Abstract: A sealing wedge-lock washer assembly usable in a hygienic, secure fastening system. A wedge-lock washer assembly comprises two wedge-lock components—one of which is a sealing wedge-lock washer having a wedge-lock cam and a sealing material bonded to its outer rim. The other component is a standard wedge-lock washer or a bolt whose head has a wedge-lock cam that engages the complementary cam on the sealing wedge-lock washer. The resulting sealing wedge-lock washer assembly locks a bolt in a secure joint that is hygienically sealed from the intrusion of contaminants by the sealing material.

Abstract: A conveyor employs a low-tension, direct drive conveyor belt, and a position limiter assembly. The position limiter assembly includes a primary position limiter and a secondary position limiter. The primary position limiter provides line of contact engagement with the conveyor belt while the secondary position limiter has an extended, static limiting surface for engaging the conveyor belt if the conveyor belt disengages from a drive sprocket prior to the line of contact with the primary position limiter.

Abstract: A conveyor employs a low-tension, direct drive conveyor belt, and a snap-on position limiter for ensuring proper engagement of the belt and a drive sprocket. The position limiter includes a body, a limiting surface and a snap clap opposite the limiting surface for snapping the position limiter to a mounting shaft. The position limiter may include a mounting arm for mounting a conveyor belt scraper at the front of the position limiter. Mounting plates at the end of the conveyor support a mounting shaft for mounting the position limiter or other conveyor components in place relative to the drive sprocket.

Abstract: A conveyor employs an infeed assembly and outfeed assembly, each comprising a nosebar assembly that may be mounted to a conveyor frame to transition a conveyor belt between a returnway and a carryway. The outfeed assembly further includes a drive sprocket and a limiter to ensure engagement of drive elements on the conveyor belt with the drive sprockets. A limiter plate ensures proper placement of the limiter relative to the drive sprocket. The infeed assembly and outfeed assembly components may be easily mounted to and removed from the conveyor frame to facilitate replacement, cleaning or maintenance.

Abstract: A cleanable belt conveyor having a locking mechanism. A locking mechanism including two locking protrusions is used to lock a first conveyor component to a second conveyor component. The locking mechanism comprises a base plate having at least one opening for receiving a locking protrusion and at least one handle plate including the locking protrusion. A saddle extending from one side of the base plate cradles the locking protrusion and may engage a pivot post of a conveyor component.
